Abstract
A method and system for detecting the presence of an object caught between an automotive window and its respective frame includes a sensor mounted on a drive motor that drives a regulator to move the window upward and downward. The sensor senses a resistive torque applied against the regulator and generates a signal having a value proportional to the amount of resistive torque sensed. The signal is transmitted to a control circuit which then determines whether or not an object is caught between the window and its respective frame.
